Spotify Premium vs Tidal ... opinions?

I prefer black and white over 1080P. Looks awesme on my 19 inch magnavox.

Guys - if you had a TV and you could just see three colors, you would sit down and realize something is wrong and work until you can see the other 4 colors. So, if you have a stereo and you cannot discern the difference between a 320 mps signal and a 44.1k signal, you should be looking for the rest of the signal. If you don't understand and really want to, go to a dealer (not Mangolia in Best Buy) and hear a very good system, set up properly. Bring your favorite song in MP3 and in 44.1 and you will have a wonderful education. It is like the touch of a women and watching a DVD. Lets get real.

Everyone who cant hear the difference between an mp3 and a cd.

the cost of one CD...

You really want to keep away from USB.  Pono is great but it is not a streaming service.  It is a digital walkman.  You need to store music on it, it cant stream - but its sound is SOTA.  I love mine.  

Before just settle on USB to dac (note, many dacs DO NOT have USB so you need to add yet another device in the line, and more cables.. more expense for a poorer interface-an interface effected by every single function your PC will perform, and USB was created for peripherials, not music...and sound cards were specifically designed for music, not attaching a printer), just try a spdif solution.  I love how everyone just goes to USB and swears its the best, never trying spdif, which is so much better, I chuckle.
